App crashes on physical device but works in simulator

Consider this:

Exception Type:  EXC_CRASH (SIGABRT)

It typically means that the app has deliberately crashed (trapped) by calling abort. Now this:

Thread 0 Crashed:

Frame 8 suggests that something has thrown a language exception [1] which has gone unhandled and hence trapped. I don’t have any insight beyond that because I don’t maintain expertise in third-party tooling.

Your third-party tooling probably has standard techniques for investigating language exceptions like this, and I recommend that you research those via the support channel for that tooling.

[1] I’m not sure if this is one of ours, per What is an exception?, or a C# language exception.
